This might be possible (I don't know).
But if you are using a classic tape backed HSM, the tape will do a simple
lossless compression on it and will be faster.
If you end up hacking in your own, look at pbzip (bzip) or pigz(gzip) for
multi-threaded compression compatible with their common serial counterparts.
